Joined by his friends, Sam and Riya, Will journeys through a new portal and arrives at the Tusk Temple in search of Maji the time-travelling elephant. But the temple is in danger. The only way to save it is for Will to undergo the Night Zookeeper trial - facing leaps over bottomless caverns, impossible puzzles, and an ultimate test in bravery.
